    INVESTIGATION EVALUATION: OUR LABORATORY EVALUATION OF THE PRODUCT SAID TO BE INVOLVED CONFIRMED THE CUTTING WIRE SECURING COMPONENT LOCATED NEAR THE DISTAL END OF THE SPHINCTEROTOME HAS DISCONNECTED FROM THE CATHETER. THE CUTTING WIRE IS INTACT AND REMAINS SECURELY ATTACHED TO THE SPHINCTEROTOME AT THE PROXIMAL END. HOWEVER, DUE TO THE CATHETER AND SECURING COMPONENT DISCONNECTION, THE DISTAL END OF THE CUTTING WIRE IS NO LONGER CONNECTED TO THE SPHINCTEROTOME CATHETER AT THE DISTAL END. NO SECTION OF THE SPHINCTEROTOME DEVICE IS MISSING. A PRODUCT DISCREPANCY OR ANOMALY THAT COULD HAVE CONTRIBUTED TO THIS REPORTED OCCURRENCE WAS NOT OBSERVED. THE DEVICE HISTORY RECORD FOR THE LOT NUMBER SAID TO BE INVOLVED WAS REVIEWED. A DISCREPANCY OR ANOMALY WAS NOT OBSERVED WITH THE PRODUCT THAT WAS RELEASED FOR DISTRIBUTION. INVESTIGATION CONCLUSIONS: A DEFINITIVE CAUSE FOR THE REPORTED OBSERVATION COULD NOT BE DETERMINED BECAUSE THE CONDITION OF THE PRODUCT SAID TO BE INVOLVED PROHIBITED A COMPLETE EVALUATION. A DISCREPANCY OR ANOMALY THAT COULD HAVE CONTRIBUTED TO THE REPORTED OBSERVATION WAS NOT OBSERVED DURING OUR LABORATORY ANALYSIS OF THE RETURNED PRODUCT. SEPARATED OF THE CUTTING WIRE SECURING COMPONENT AND THE CATHETER CAN OCCUR IF THE TIP OF THE SPHINCTEROTOME IS OVER FLEXED. THE INSTRUCTIONS FOR USE CAUTION THE USER NOT TO OVER FLEX OR BOW THE TIP BEYOND 90 DEGREES, AS THIS MAY DAMAGE THE SPHINCTEROTOME. THIS TYPE OF DAMAGE CAN OCCUR IF THE DISTAL END OF THE CATHETER IS SHAPED MANUALLY. THIS SPHINCTEROTOME CATHETER IS PRE-CURVED AND IS PROVIDED WITH A PRE-CURVED STYLET IN THE DISTAL TIP OF THE CATHETER. THIS OBVIATES THE NEED FOR MANUAL FORMATION. THE INSTRUCTIONS FOR USE CONTAIN THE FOLLOWING COMMENT: "NOTE: DO NOT APPLY MANUAL PRESSURE TO TIP OR CUTTING WIRE OF THE SPHINCTEROTOME TO INFLUENCE ORIENTATION, AS THIS MAY RESULT IN DAMAGE TO DEVICE". IF THE ELEVATOR OF THE ENDOSCOPE REMAINS IN THE CLOSED/UP POSITION WHEN RETRACTION OF THE SPHINCTEROTOME IS ATTEMPTED AND ADDITIONAL PRESSURE IS APPLIED, THIS COULD HAVE CONTRIBUTED TO SEPARATION OF THE CATHETER AND CUTTING WIRE SECURING COMPONENT. THE INSTRUCTIONS FOR USE CAUTION THE USER THE ELEVATOR SHOULD REMAIN OPEN/DOWN WHEN ADVANCING OR RETRACTING THE SPHINCTEROTOME. THIS ACTIVITY WILL AID IN DEVICE PRESERVATION. OTHER FACTORS THAT CAN CONTRIBUTE TO SEPARATION OF THE CUTTING WIRE SECURING COMPONENT AND THE CATHETER INCLUDE MANIPULATING THE HANDLE WITH THE CATHETER IN A COILED POSITION OR WITH THE PRE-CURVED STYLET INSIDE THE CANNULATING TIP. THE INSTRUCTIONS FOR USE ADVISE THE USER TO UNCOIL AND STRAIGHTEN THE SPHINCTEROTOME UPON REMOVING THE DEVICE FROM THE PACKAGING. THE USER IS THEN INSTRUCTED TO CAREFULLY REMOVE THE PRE-CURVED STYLET FROM THE CANNULATING TIP. THE INSTRUCTIONS FOR USE CONTAIN THE FOLLOWING COMMENT: "NOTE: DO NOT EXERCISE HANDLE WHILE DEVICE IS COILED OR PRE-CURVED STYLET IS IN PLACE, AS THIS MAY CAUSE DAMAGE TO SPHINCTEROTOME AND RENDER IT INOPERABLE." PRIOR TO DISTRIBUTION, ALL D.A.S.H. PRE-LOADED WITH ACROBAT WIRE GUIDE SPHINCTEROTOMES ARE SUBJECTED TO A VISUAL INSPECTION AND FUNCTIONAL TEST TO ENSURE DEVICE INTEGRITY. THE FUNCTIONAL TEST INCLUDES BOWING THE SPHINCTEROTOME TO ENSURE THE DISTAL END RESPONDS TO HANDLE MANIPULATION. A REVIEW OF THE DEVICE HISTORY RECORD CONFIRMED THAT THE LOT SAID TO BE INVOLVED MET ALL MANUFACTURING REQUIREMENTS PRIOR TO SHIPMENT. CORRECTIVE ACTION: A REVIEW OF THE COMPLAINT HISTORY WAS CONDUCTED. THE LIKELIHOOD OF OCCURRENCE IS CONSIDERED RARE. CORRECTIVE ACTION IS NOT WARRANTED AT THIS TIME BASED ON THE QUALITY ENGINEERING RISK ASSESSMENT. QUALITY ASSURANCE WILL CONTINUE TO MONITOR FOR COMPLAINT TRENDS AND REASSESS THE RISK ASSESSMENT RESULTS AS POST MARKET FEEDBACK CONTINUES TO BECOME AVAILABLE.
